I already had a Tiered account in the past when there was no other option.
When they came out with the new Wager option, they allowed a 2nd account so you could try both.
So now I have 2 accounts and I send exactly 50% of my traffic to each account, then over time I can test both revenue models.
I don’t know if they still allow you to open 2 accounts, but if so I think that’s the best option so you can test which is better for your traffic.
Right now the lifetime earnings from my wager model account has made 100 times more than my tier model account, but I haven’t sent them enough traffic to know for sure which one is best over time so I’m still splitting the traffic.
